SPRING SEAT FOR TRUCKS AND AUTOMOBILES.

Application led October 16, 1924. Serial No. 743,934.

T o all 'whom t 'may concern:

Be it known that I, HARLEIGH R. HOLMES, a citizen of the United States, residing at Littleton, county of Arapahoe, and State of Colorado, have invented certain new and useful Improvements in Spring Seats Jforl drawings, and tothe characters of reference e and, therefore, derives no i It is thev object of thisy invention to so marked thereon, which form a part of this specification.

This invention relates to spring seat construction. l

The ordinary truck and automobile is provided with seats having a back cushion that is stationary with respect to the automobile body and a spring seat cushion whic rests upon a support that is also stationary with respect to the automobile body.v As the seat cushions are provided with springs which yield, and

senger sits upon the seat cushion, it 1s evident that there willl be relative movement between the back cushion and the occupant of the seat,.who, if he rests his back against the back cushion, will producel a friction which soon wears out the cushion and the occu ants clothes.

W en trucks are provided with seats ofA the type referred to, the driver soon learns that he cannot, with any degree of comfort, rest his back against the back cushion benefit therefrom.

construct an automotive vehicle seat that the occupant thereof may make full use of the back cushion without subjecting it or his own clothesto excessive ,wear nor himself to discomfort. v

My invention, briefly described, consists in forming the seat in two parts, one being a frame that rests uponv the automobile body frame and the other a similar framework supported rom the first one by means of springs, and having securedto one side thereof a back cushion. The seat cushion rests upon the frame to which the back cushion is secured. By this means the 0ccupant has the benefit of thev spring action without `being subjected to rubbing action since theidriver or the pasp 5 and 6, which cushion (not shown) due to therelative movement of the surface of the seat cushion and 'the back cushion.

My invention can scribed and will be most readily understood when reference is had to the accompanying drawing, in which the preferred embodiment thereof is illustrated, and in which:

Fig. 1 is a perspective view of my improved seat showing the same with the seat cushion removed and a portion of the bottom oi the seat cushion support broken awa.

Fig. 2 'is a detail .taken on line 2-2, Fig. 1; Fig. 3 is a view taken on line 3 3, Fig. 1; and i Fig. 4 is a section taken on line 4 4, Fig. 2.

The seat consists of a rectangular frame h of angle iron consisting of sides 1, 2 and ends 3, 4. The sides and ends are preferably welded so as to form a rigid rectangular structure. Midway between the end ieces 3 and 4, I secure two transverse pieces serve as tie-rods for the side members 1 and 2 and as supports for the 'blocks 7. lThe blocks 7 have their upper sides concave and su port the springs 8, which are clamped tlliereto by means of bolts 9 whose upper ends pass through the transverse bars 10. I

The seat proper comprises" a second framework comprising sides 11, 12 and ends 13, 14, preferably welded together at the corners. Near each end of .the end bars 13 I securev a U-shaped bracket 15 by means of rivets 16. A bolt 17 extends between the arms of cach bracket and serves as a pivot for a air of shackle links 18 between and to which the ends of the springs are connected.-

The sides 11, 12 and ends 13, 14 are connected by means of transverse' straps v19 and springs 20, upon which the seatrests. Secured to the rear ends of end members 13 and 14 are vertical -members 21 whose upper ends are -oined by an angle 22. Braces 23 connect the vertical members 2 1'with the end members 14 and hold the frame 21, 22 in vertical be most clearly de-v col position. A back cushion 24 is secured 1n place on frame 21, 22.

for the ordinaryseat and back cushions ofa truck or other automobile vehicle. The occupant of this improved seat has a comortable seat to sit on and has the benefit of the springs 8, as Well as the springs 20. It

is evident that since the seat cushion is not 1 depended upony to furnish the spring action and can therefore be made Without s rings, the occupant may lean against the bac cush- -ion 24 without dan er of Wearing out his clothes or the cushion, and Withoutv causing the discomfort that is experienced in seats where the seat cushions are provided' With' springs.

Although my seat mayA be employed in connection with ordinary automobiles as Well as 'With trucks, itis, however, in vconnection with trucks that my seat finds its greatest field of usefulness, as trucks have, of necessity, very stiff springs that are of little or no efect in making it ride easy in "the sense in which springs on ordinary passenger cars function. On trucks, therefore,

the driver and passengers must depend upon the springs in the seat construction for the elimination of shocks and vibrations, and it supported from the'ends of shackles (18) which are pivoted to the ends A is forv this reason'that the usualv seat con-v struction is unsatisfactory.

Having now. described my invention,
